摘要
The g-C3N4 nanosheets were synthesized by a multistage program calcination with different heating rate, which was an easy, low-cost, and quick method. The morphology and structure of samples were characterized by various techniques. The performance evaluation of the samples was tested by degrading Rhodamine B, Methylene Blue, Tetracycline Hydrochloride and P-Nitrophenol in visible light. The results show that the photodegradation properties of TP-g-C3N4 prepared by multistage program calcination are the best than others. In particular, the degradation rate of TP-g-C3N4 to Rhodamine B reached 99.6% in just 4 min. TP-g-C3N4 catalyst has excellent stability and recycling performance. According to free radical capture experiments, •O2− may be the main active species for pollutant degradation. The possible photocatalytic degradation mechanism was also discussed. Due to the high specific surface area and a narrow band gap, the TP-g-C3N4 becomes a promising photocatalyst.
